Tmux battery status for OSX

Enables displaying battery percentage and status icon in Tmux status-right.

Battery full:

Battery discharging, custom discharge icon:

Battery charging:

This is done by introducing 2 new format strings that can be added to status-right option:

• #{battery_icon} - will display a battery status icon
• #{battery_percentage} - will show battery percentage

Usage

Add #{battery_icon} or #{battery_percentage} format strings to existing status-right Tmux option. Example:

# in .tmux.conf
set -g status-right "Batt: #{battery_icon} #{battery_percentage} | %a %h-%d %H:%M "

Installation with Tmux Plugin Manager (recommended)

Add plugin to the list of TPM plugins in .tmux.conf:

set -g @tpm_plugins "                 \
  tmux-plugins/tpm                    \
  tmux-plugins/tmux-battery-osx       \
"

Hit prefix + I to fetch the plugin and source it.

If format strings are added to status-right, they should now be visible.

Manual Installation

Clone the repo:

$ git clone https://github.com/tmux-plugins/tmux-battery-osx ~/clone/path

Add this line to the bottom of .tmux.conf:

run-shell ~/clone/path/battery_osx.tmux

Reload TMUX environment:

# type this in terminal
$ tmux source-file ~/.tmux.conf

If format strings are added to status-right, they should now be visible.

Changing icons

By default, these icons are displayed:

• charged: "🔋"
• charging: "⚡"
• discharging: (nothing shown)

You can change these defaults by adding the following to .tmux.conf (the following lines are not in the code block so that emojis can be seen):

• set-option -g @batt_charged_icon "😎"
• set-option -g @batt_charging_icon "👍"
• set-option -g @batt_discharging_icon "👎"

Reminder: OSX allows you to insert various emojis by pressing Cmd+Ctrl+Space.

Don't forget to reload TMUX environment ($ tmux source-file ~/.tmux.conf) after you do this.

Known issues

• Battery icon change most likely won't be instant.
  For example, when you un-plug power cord it will take some time (15 - 60 seconds) for the icon to change. This depends on the status-interval TMUX option. Setting it to 15 seconds should be good enough.

Other plugins

• logging - easy logging and screen capturing
• online status - online status indicator in Tmux status-right. Useful when on flaky connection to see if you're online.
